.SH DESCRIPTION
This implementation provides functions which return properties
set in the WINDOW structure, allowing it to be \*(``opaque\*('' if
the symbol \fBNCURSES_OPAQUE\fR is defined:
.TP 5
\fBis_cleared\fR
returns the value set in \fBclearok\fR
.TP 5
\fBis_idcok\fR
returns the value set in \fBidcok\fR
.TP 5
\fBis_idlok\fR
returns the value set in \fBidlok\fR
.TP 5
\fBis_immedok\fR
returns the value set in \fBimmedok\fR
.TP 5
\fBis_keypad\fR
returns the value set in \fBkeypad\fR
.TP 5
\fBis_leaveok\fR
returns the value set in \fBleaveok\fR
.TP 5
\fBis_nodelay\fR
returns the value set in \fBnodelay\fR
.TP 5
\fBis_notimeout\fR
returns the value set in \fBnotimeout\fR
.TP 5
\fBis_pad\fR
returns \fBTRUE\fP if the window is a pad
i.e., created by \fBnewpad\fP
.TP 5
\fBis_scrollok\fR
returns the value set in \fBscrollok\fR
.TP 5
\fBis_subwin\fR
returns \fBTRUE\fP if the window is a subwindow,
i.e., created by \fBsubwin\fP or \fBderwin\fP
.TP 5
\fBis_syncok\fR
returns the value set in \fBsyncok\fR
.TP 5
\fBwgetdelay\fR
returns the delay timeout as set in \fBwtimeout\fP.
.TP 5
\fBwgetparent\fR
returns the parent WINDOW pointer for subwindows,
or NULL for windows having no parent.
.TP 5
\fBwgetscrreg\fR
returns the top and bottom rows for the scrolling margin
as set in \fBwsetscrreg\fP.
.SH RETURN VALUE
These functions all return \fBTRUE\fP or \fBFALSE\fP, except as noted.
.SH NOTES
Both a macro and a function are provided for each name.
.SH PORTABILITY
These routines are specific to ncurses.
They were not supported on Version 7, BSD or System V implementations.
It is recommended that any code depending on ncurses extensions
be conditioned using NCURSES_VERSION.
